Thanks! I was already in the process of removing the bedding from the coop and didn't see your answer. I will just let them spread it around their run now and not haul the last few loads to my garden tomorrow.
Also, whenever anyone talks about "just pluck the hens from the roosting bar at night and treat them", obviously has much calmer chickens than I do! The 2 chickens with scaly leg mites are new to the flock and not used to being handled by me as much. So, there was a lot of flapping and squawking and one container of olive oil spilled all over the coop floor. It had some tea tree and lavender oil in it, so at least it smells good in there now.

I left the rest of the chickens, who aren't actually infected (that I know of) to treat in the daylight! Lol
